The On Running Cloudmonster 3 arrives in a striking dark purple mesh upper, offset by a periwinkle-blue panel that sweeps from heel to mid-foot along both sides. It's a maximalist running trainer built for those who want serious cushioning underfoot without sacrificing standout style, and the colour-blocked finish makes it easy to spot on the shelf and on the road.
The upper combines a fine woven mesh across the toe box, vamp and heel counter with a black synthetic overlay that frames the lace area in a jagged, zig-zag edge. Flat woven laces in mixed purple and white tones thread through fabric loops and eyelets, while a padded pull tab at the heel collar makes it easy to step in and out. Reflective silver 'On' branding, the 'ON RUNNING' wordmark and 'SWISS ENGINEERING' text with a flag icon on the tongue all point to the Swiss brand's engineering-led approach to running footwear.
What really sets the Cloudmonster 3 apart is its midsole. This is On's Helion Cloudtec system in its most exaggerated form: a thick, white foam unit with an open-lattice structure of elongated hexagonal and oval cavities running the full length of the sole. Underneath, black rubber lugs are arranged in a geometric tread for grip, with exposed rubber at the heel for added durability where it's needed most.
This is a shoe suited to runners who prioritise cushioning and rebound over a minimalist ride, whether that's for long-distance training or simply all-day comfort. It also works well as an off-duty trainer for anyone drawn to the chunky, technical running-shoe look that's become a wardrobe staple in its own right.
